I'm desperately looking for a way to "decompile" a video, making a slideshow of still images.

My guess was that, to get best results, I should extract only KEYFRAMES and then choose the best shots and discard the rest.

After 10 days of research, I'm where I was in the beginning(

Vdub can only save ALL the frames, overflowing my HDD and making a zillion of stills, impossible to work with (the file system becomes very slow with 0.7 million files in one folder)

I tried Adobe Premiere, different tools, converters, frameservers with scripts...

I even tried a macro recorder to make
1. Vdub go to a next keyframe
2. copy frame to clipboard
3. switch to Paint
4. paste the image
5. save the file
6. copy the file to a file with a unique name
7. repeat the sequence N times
only to find that there are no good macro recorders/players these days...

SOMEBODY tell me, how to get it done!....

the video file format is VCD .dat

keyframes are irregular: 1/15 mostly, but 9 or 3...etc sometimes

I'd like to get frames in .bmp (lossless)...

Please read and follow forum rules, specifically, rule 9: use a proper thread title. You can use the edit feature to fix this one. Something like "How do I extract only the keyframes from a video?"

Thank you and welcome to the forum.

Vdub can only save ALL the frames
Naah ;>}

From the "Video" dropdown menu, click on "Framerate" and under "Framerate Decimation", choose "Decimate by" and enter the desired number of frames you'd like to skip between "captured" frames...

You can install ffdshow, then under its settings you can enable "Grab." When you play a video or a portion from which you want frames, they're stored in the predetermined directory.
